several thousand volts (2.5 kV, say) at a few hundred mA (up to around 1/2
Amp).  Magnetrons are fairly efficient (say 80%), so a 650Watt oven will
have about 800-900 Watts DC going into the tube.  One tricky aspect when
doing these calculations is that ovens run with a half wave doubler, so the
peak current/average (or peak/RMS for that matter) current is thrown off.
